RESUMO

OBJECTIVES: To assess the impact of using data from the National Death Index (NDI) of Spain to estimate breast cancer survival rates among residents of Girona and Zaragoza diagnosed in 1995-1999. METHODS: This was an observational, longitudinal epidemiologic study, using two population- based cancer registries. Data collected were of female residents of Girona or Zaragoza who had been diagnosed with breast cancer in 1995-1999. Observed and relative 5-year survival rates were estimated, first using the information available from the Girona and Zaragoza cancer registries, and then with the inclusion of NDI data. The 5-year relative survival rate and corresponding 95 percent Confidence Intervals were estimated using the Hakulinen method. The Kaplan-Maier method and Log Rank test were used to compare survival curves. RESULTS: No statistically significant difference in survival curves was observed in Girona for the data obtained before and after cross-matching with the NDI. However, there was a significant difference in Zaragoza. A comparison of the relative survival rates of each of the two registries before NDI cross-matching showed differences of 3.9 percent (5-year) and 16.1 percent (10-year) between the two, whereas after the cross-match, the difference was only 0.5 percent (5-year) and 1.2 percent (10-year). CONCLUSIONS: In Spain it is imperative that there be systematic use of NDI data to supplement cancer registries, so that comparisons of relative survival rates between registries can be improved.


OBJETIVO: Evaluar el efecto de utilizar los datos del Índice Nacional de Defunciones (IND) de España para estimar las tasas de supervivencia de cáncer de mama en las mujeres residentes en Girona y Zaragoza que recibieron el diagnóstico de cáncer de mama en 1995-1999. MÉTODOS: Se realizó un estudio epidemiológico observacional y longitudinal basado en el empleo de los registros de cáncer de mujeres residentes en Girona y Zaragoza que habían recibido el diagnóstico de cáncer de mama en 1995-1999. Se estimaron las tasas de supervivencias observada y relativa a 5 años, primero según la información disponible en los registros de cáncer de Girona y Zaragoza y luego con la inclusión de los datos del IND. Se calcularon las tasas de supervivencia relativa a 5 años y sus correspondientes intervalos de confianza de 95 por ciento por el método de Hakulinen. Las curvas de supervivencia se compararon por el método de Kaplan-Maier y la prueba de rangos logarítmicos. RESULTADOS: No se encontraron diferencias estadísticamente significativas entre las curvas de supervivencia de Girona antes y después de emparejar lo datos locales con los del IND; sin embargo, hubo diferencias significativas entre las curvas de Zaragoza. Al comparar las tasas de supervivencia relativa de cada uno de los registros antes de emparejarlos con los datos del IND se encontraron diferencias de 3,9 por ciento (a 5 años) y 16,1 por ciento (a 10 años), mientras que después del emparejamiento, la diferencia entre ellas fue solamente de 0,5 por ciento (a 5 años) y 1,2 por ciento (a 10 años). CONCLUSIONES: En España es imperativo el empleo sistemático de los datos del IND para complementar los registros de cáncer de manera de mejorar las comparaciones de las tasas de supervivencia relativa cuando se utilizan diferentes registros.

RESUMO

The aim of this work is to make known the multicentric project AMCAC, whose objective is to describe the geographical distribution of mortality from all causes in census groups of the provincial capitals of Andalusia and Catalonia during 1992-2002 and 1994-2000 respectively, and to study the relationship between the sociodemographic characteristics of the census groups and mortality. This is an ecological study in which the analytical unit is the census group. The data correspond to 298,731 individuals (152,913 men and 145,818 women) who died during the study periods in the towns of Almeria, Barcelona, Cadiz, Cordoba, Girona, Granada, Huelva, Jaen, Lleida, Malaga, Seville and Tarragona during the study periods. The dependent variable is the number of deaths observed per census group. The independent variables are the percentage of unemployment, illiteracy and manual workers. Estimation of the moderated relative risk and the study of the associations among the sociodemographic characteristics of the census groups and the mortality will be done for each town and each sex using the Besag-York-Mollie model. Dissemination of the results will help to improve and broaden knowledge about the population's health, and will provide an important starting point to establish the influence of contextual variables on the health of urban populations.
